"Average annual solar radiation arriving at the top of the Earth's atmosphere is roughly 1361 W/m . The Sun's rays are attenuated as they pass through the atmosphere, leaving maximum normal surface irradiance at approximately 1000 W/m at sea level on a clear day. When 1361 W/m is arriving above the atmosphere (when the sun is at the zenith in a cloudless sky), direct sun is about 1050 W/m , and global radiation on a horizontal surface at ground level is about 1120 W/m . Th… " - Intensity of the sun
